Don't overlook the fact that the case neck needs to have a good grip on the bullet for consistant ingition. I've read that you should have from .5 to 1 full caliber of bullet in the neck. Stated differently, a .308 bullet should be in the case to a depth of at least .154. I can't seat my 168's out far enough to engage the rifling in my 700VS. The leade or freebore is too long. It still shoots fine, tho'.
